What is Flooding in Distillation Column?

Flooding in a distillation column is a phenomenon that occurs when the vapor velocity through the column becomes excessive, hindering the proper functioning of the trays or packing. Flooding is a critical issue that can lead to a loss of separation efficiency and impaired column performance.
Flooding results in the accumulation of liquid on trays or packing to a level where it impedes the upward flow of vapor. This excessive liquid holdup prevents efficient vapor-liquid contact and disrupts the separation of components.
Flooding leads to a loss of tray efficiency as the vapor is unable to effectively disperse through the liquid. This results in decreased mass transfer between the vapor and liquid phases, negatively impacting the separation of components.
